在GP—y8—1型塑料大棚的基础上,根据华东地区地块小、雨水多、受部分台风影响的特点,由中国农业工程研究设计院环境工程室、安徽拖拉机厂、上海市农业局蔬菜处研究设计了GP—y6—1型和GP—y4—1型两种变型棚。由于棚型合理、抗风能力强、安装简便、农艺效果好,受到普遍欢迎;试销一年来订货已近2000套。上海郊区各县先后推广了400多套。华东各省均有大量推广;河南、湖北、四川、云南、广东、广西、甘肃、福建等省及北京、沈阳、内蒙古等军区也推广了1100余套。安徽拖拉机厂81年生产的首批样品,安装在上海市嘉定县长征公社四中大队种籽场。82年在上海已有33套经受了春秋两季的生产考验,在82年第9号、第
On the basis of GP-y8-1 plastic greenhouse, according to the characteristics of small block, heavy rain and some typhoons in East China, the project is composed of Environmental Engineering Department of China Agricultural Engineering Research and Design Institute, Anhui Tractor Factory, Shanghai Municipal Bureau of Agriculture At the study and design of the GP-y6-1 type and GP-y4-1 type two variants shed. Due to shed type reasonable, strong wind resistance, easy installation, good agronomic effect, are generally welcomed; test sales a year to order nearly 2000 sets. Shanghai suburbs counties have promoted more than 400 sets. All provinces in East China have a large number of promotion; Henan, Hubei, Sichuan, Yunnan, Guangdong, Guangxi, Gansu, Fujian and other provinces and Beijing, Shenyang, Inner Mongolia and other military regions have also promoted more than 1,100 sets. The first batch of samples produced in 81-year tractor factory in Anhui Province was installed in the seed market of the Fourth Brigade of Changzheng Commune, Jiading County, Shanghai. In 1982, 33 sets of production have been tested in spring and autumn in Shanghai. In 1982, No. 9,
